Research ArticleOpen accessEvery word in the titleFractionated Distillation Behavior and Aroma Component Enrichment of Citronella Oil (Cymbopogon winterianus Jowitt) from West SumatraDaimon Syukri, Anni Faridah, Bayu Indra Lesmana et al.This study aimed to separate the constituent components of citronella oil into several fractions with high purity and to identify the characteristics of the resulting fractions. The research was conducted using an exploratory approach to investigate the fractionation behavior of citronella oil more deeply. The raw materials were citronella oils obtained from three regions in West Sumatra: Batusangkar, Solok, and … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 10 Aug 2026 · 849 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Polysaccharide-Rich Fraction Derived from Oviductus ranae with Antioxidant and Immunomodulatory PotentialsXiaojin Yu, Xinyu Wang, Xinyu Liu et al.Oviductus ranae, an animal-based traditional Chinese medicinal material listed in Chinese Pharmacopeia is widely consumed as tonic, approximately twenty Oviductus ranae-related functional foods have been approved on the market by National Medical Products Administration in China. Proteins are well-defined bioconstituents in Oviductus ranae, little information is availabe on its polysaccharides. In present work, a Polysaccharide-Rich fraction (POR-3) was fractionated from … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 13 Sep 2020 · 6,620 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetermination of the Mutagenicity of 2-aminoanthracene Using Chicken Hepatic S-9 FractionVladimir A. Chistyakov, Alexander V. Usatov, Aleksander I. Klimenko et al.The abundance of potential genotoxins makes it necessary to improve microbial test systems that allow to identify these substances quickly. At the same time, the methodology of metabolic activation of promutagens in vitro is very important. Microsomal preparations of rodents, which are generally used for that, have significant disadvantages associated with the potential health risks of the inducers of the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 16 Nov 2018 · 7,192 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFractionation of Organic Carbon in Arial Beel Wetland Soils of BangladeshMonera Akter Eva, Mahmudul Islam Piash, Md. Faruque Hossain, Zakia ParveenA study was conducted to determine the organic carbon fractions in the vertical sections of a benchmark wetland soil of Bangladesh (Arial Beel) and their dynamics that directly affect the biogeochemistry of soil, water and plant biomass ecosystem. Two distinctive soil series viz. Sara and Arial are characterized such as pH, moisture content, textural class, CEC, organic carbon (SOC), bulk … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 4 May 2018 · 9,134 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleAnalytical Solutions of Riccati Fractional Equation with Coefficients Satisfying Differential Conditions with Arbitrary FunctionKhaled K. JaberNew exact solutions of the Fractional Riccati Differential equation are presented. Exact solutions are obtained in cases that the coefficient functions and an arbitrary function satisfy some differential conditions. In view of the conditions imposed on Riccati equation's coefficients we define and formulate the coefficients of the Riccati equation to obtain the differential cases, for each case the general solution … …Journal of Mathematics and Statistics, Vol. 13, Issue 4 · 27 Dec 2017 · 7,211 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn Almost Periodic Solutions of Abstract Semilinear Fractional Inclusions with Weyl-Liouville Derivatives of Order γ ∈ (0, 1]Marko KostićThe main aim of this paper is to examine the existence and uniqueness of almost periodic solutions for a class of (semilinear) fractional relaxation inclusions with Stepanov almost periodic coefficients. We deal with the Weyl-Liouville fractional derivatives of order γ ∈ (0, 1], paying special attention to the analysis of semilinear differential inclusions of first order.
